It looks like the tcx framebuffer is capable of supporting 24 bit
   color, but a tcx framebuffer under netbsd will only support 8 bit
   color.  (This seems to be true in 1.4, anyway.)
   
   Is the tcx framebuffer likely to be supported better anytime soon if I
   don't find time to write the relavent code?  What code does need to be
   written to make it work?
   
the tcx driver is, as i recall, very basic -- just enough to work,
but none of the smarts available through the hardware.  i'm not aware
of anyone working on it so anything you do to make it better would be
excellent!
